The 2-year old girl and her mother were visiting a bank in Vicenza, Italy. The young girl got bored and went wandering. She found an open time-lock safe, went inside, and closed the door. The safe was made so that, once closed, it could not be re-opened for 40 minutes.
Firefighters rushed to the scene. They used a hydraulic tool to break the safe open. The girl emerged scared, but unharmed 15 minutes later.
Considering how small the safe is, I wonder how she had enough air to breathe for that long.
